Hello all,<br><br>we are using rsync to produce a replica of our filesystem.<br><br>it&#39;s very important for us to be sure that the files replicated on the remote backup host are left in a consistent state as we may need to boot services from those files (configs, logs, etc)!<br>
<br>right now we use a &#39;greedy approach&#39;... we stop all important services (dhcpd, squid, sendmail, etc) just to minimize the possibility of copying to the backup a file that was being written.<br><br>Could we be over doing it ? Are we exagerating ?<br>
<br>An example: if we do not stop sendmail were rsync&#39;ing can we be sure that the queues on the replica machine are in a consisten state ?<br><br>same for dhcpd leases or squid&#39;s cache ?<br><br>We would really like to leave all those important services up but we are really affraid of producing a corrupted replica...<br>
<br>can anyone comment on this ? is rsync imune to this kind of problem ?<br><br>thank you very much.<br><br>Joao<br><br>
